Hi, this forum is for software developers who are using the Open Protocol Specification documentation to assist them in developing systems, services, and applications that are interoperable. The Open Protocol Specifications can be found at: http://msdn2.microsoft.com/en-us/library/cc203350.aspx. Since your post does not appear to be related to the Open Protocol Specification documentation set we would appreciate it if you could try the Windows 7 Home page (http://www.microsoft.com/windows/windows-7/default.aspx) instead to find the information you are looking for. Thanks!
There is related content on the Windows 7 Q & A - it will probably be necessary to reinstall your former operating system.
